Well I finally made it there on a weekday at lunchtime and was rewarded with a damn fine sandwich, even though I ate it after it had cooled down quite a bit (picnicking on the Common.)
It was about 11:15 and there was no line, although a line started to pick up after I ordered.
I overheard someone who looked like a manager talking to a customer about how business has been really slow and if it doesn't pick up they're going to have to close. It might have just been hyperbole, but you never know.
Thanks for the tip, Chowhounds- oh, and how do you actually pronounce it?
